To obtain real-life data on the most common practices used for management of incidental durotomy (ID) in France. ⋯ This nationwide survey reflects the lack of a standardized management protocol for ID. Practices among surgeons remain very heterogeneous. Further consensus studies are required to develop a standard management protocol for ID.

Guillain-Barre syndrome (GBS) is a rare but serious disorder involving peripheral nerve inflammatory demyelination characterized by acute onset tetraparesis and areflexia. Generally, GBS is preceded by a bacterial or viral infection, and post-traumatic or postsurgical GBS is rarely seen. ⋯ We report the first case, to our knowledge, with post-traumatic GBS after craniocerebral gunshot injury. We want to indicate the possibility of post-traumatic GBS in cases of unexplained quadriparesis or quadriplegia after trauma or surgery.

Case Reports
Tethered cord syndrome caused by duplicated filum terminale in an adult with split cord malformation.
Tethered cord syndrome (TCS) is a clinical diagnosis of progressive neurologic aggravation of the lower spinal cord due to a traction on the conus medullaris. Untethering surgery is effective for most TCS; however, when anatomic variations of spinal cord and filum terminale (FT) exist, regular untethering may lead to a failed outcome. ⋯ This is the first documented adult of duplicated FT with preoperative radiologic evidence and reported in association with SCM as a cause of TCS. When SCM exists, a careful observation for duplicated FT is warranted on preoperative magnetic resonance imaging and during surgery. Complete transection of the double FT under intraoperative neurophysiologic monitoring is the best treatment for this anomaly.

Resection of deep medial frontal and parietal arteriovenous malformations (AVMs) is often challenging due to a tangential angle of attack and deep, narrow working corridor. Adequate visualization of the AVM and its feeding arteries without brain retraction is of particular importance when operating in or near eloquent cortical areas, where brain manipulation could inadvertently result in neurologic deficits. The aim of this paper is to provide a step-by-step description of surgical approach and report our experience with the contralateral transfalcine approach for resection of deep-seated parasagittal AVMs. ⋯ The contralateral transfalcine approach is a useful technique in the cerebrovascular surgeon's armamentarium for management of deep-seated medial frontal, parietal, and cingulate gyrus AVMs in or around eloquent brain areas, allowing to minimize normal brain retraction and avoid associated neurologic deficits.

Tuberculum Sellae Meningiomas inPregnancy: 3 Cases Treated in the 2nd Trimester & Literature Review.
Tuberculum sella meningiomas typically present with progressive visual loss. It is also known that meningiomas can become symptomatic during pregnancy. Herein we report on 3 patients who presented with progressive visual decline during pregnancy, prompting urgent surgical removal of their meningiomas. ⋯ Presentation of tuberculum sella meningioma during pregnancy is uncommon but not rare, accounting for 7% of women in our series. Ideally, surgery is performed in the second trimester, ensuring fetal safety while restoring maternal vision and maintaining pituitary gland function are essential. Depending on tumor size and sellar anatomy, endoscopic endonasal or supraorbital keyhole craniotomy approaches are both viable options.
